I'm trying to locate OSX drivers for this board that comes in the BIQU Magician delta printer. The PCB has "BQ111-A3" on it and the touch screen's PCB has "BQ112-A3" stenciled. The board came pre-mounted so I can't get to the underside without disassembling everything. The controller is marketed as a "BIGTREETECH 32 Bits MainBoard". Based on the GUI, as far as I can tell since there isn't a menu About option, it's running Smoothieware (I'm coming from a Marlin world so this is my best guess).

Anyone seen this board before and know what drivers I should be using to talk to it?

Under Linux, Pronterface works fine. In the kernel log, the board showed up as "CP2102 USB to UART Bridge Controller" so I figure it could be missing the VCP driver on the Mac. I installed the driver from Silicon Labs and the board is now showing up, and Pronterface is working fine.
